Abstract: The armature (2,2') of the unipolar machine is designed in the form of a disc and is arranged forming air gaps between disc-shaped stator parts (1,1') on both sides. The stator parts (1,1') can each have an annular cut-out (10) on the armature side, for an annular excitation winding (6). The pole surfaces of the stator parts (1,1') located opposite one another are magnetised in the same polarity. The armature (2,2') consists of two parallel discs, separated by an air gap or a non-magnetic intermediate layer (11). The discs carry at least one common winding (3) running through them and having windings forming a figure eight in axial section. However, two partial windings arranged behind one another in the radial direction can also be provided which are either wound or connected in the opposing direction.

Abstract: This invention relates to a method an equipment for introducing in a controlled and reproducible way, small amounts of a liquid sample into chromatographic systems, specially high resolution gas chromatographic systems and thin-layer chromatographic systems. In order to obtain sampling extremely reduced in volume and presenting maximum reliability and reproducibility, a sample container is used having a pipette-like or nozzle-like outlet neck of very small diameter, while the liquid placed in the container is submitted to at least one pressure pulse which is controlled in time and/or amplitude in order to determine emission of a corresponding and controlled quantity of liquid from the outlet neck. The pressure pulse can be a pneumatic pulse directly applied to the liquid sample in the container, or a mechanical pulse applied to the liquid sample through a device acting by magnetostriction or by a piezoelectric system.

Abstract: A process and apparatus for preparing anisotropic metallic and ceramic compositions or material includes floating zone melting of eutectics and orientation of eutectoids, as well as melting, frittering, or homogenization of the eutectoids prior to orientation. The process includes solidification of a eutectic in the presence of a thermal gradient while displacing the solidification front of the eutectic along the direction of the gradient and orienting the solid eutectoid which results by imposing a direction of growth on it by displacement of the composition itself or the temperature gradient. The eutectoids are then prepared in a reactive atmosphere within a container and the surface thereof treated in gaseous atmosphere, after which the materials are compacted by displacing them again. The apparatus for performing the process includes a double heating and cooling system and structure for translating and rotating these systems. It additionally includes a support plate for supporting the elements being oriented, the plate being attached to a displacement shaft. Electronic controls for all of the structures are connected to temperature and displacement sensors.

Abstract: The invention relates to a system of stretching overhead electric lines, more particularly high-tension lines, according to which a pilot cord or haulage cable is positioned in conventional manner over a set of top pulleys positioned at the highest point on each pylon in the line, and is then used to pull a first haulage cable or guard cable together with at least one other supplementary haulage cable, and/or supplementary guard cable. Each supplementary cable, after passing the top pulleys on which the first haulage cable of guard cable have been laid, is slid and guided downwards until it rests on pulleys underneath. in this manner, each further haulage cable is already positioned for drawing a conductor or bunch of conductors and other haulage cables if required. In the aforementioned system, it is no longer necessary to position a pilot cord for each conductor or bunch of conductors to be tensioned, but it is sufficient to position a single pilot cord on the top pulleys of the pylons, since all the conductors or bundles of conductors and/or further haulage cables are subsequently positioned automatically, starting from the pilot cord or first haulage cable, during the subsequent stage of tensioning.

Abstract: Apparatus for use in heating, ventilating, cooling and/or regulating the temperature of rooms in a building including a facade which comprises a framework of hollow posts and hollow girders is distinguished by sections of the hollow posts and hollow girders being connected to one another in flow, in fixed manner, for the conduction of a heat transfer fluid and an air stream between a delivery line and a return flow line. A distinguishing feature is that the hollow posts are constructed in two pieces or parts, each of which parts includes two channels one of which provides for the conduction of a heat transfer fluid and the other for the conduction of a further fluid such as an air stream. In the preferred form illustrated the post parts are made to be generally C-shaped in cross section. As thus provided the C-shape cross section of each part shows that it includes a double-walled base leg portion incorporating both the channel for the heat transfer fluid and a channel for further fluid. By virtue of the C-shape of the cross section of each part, two such parts, each of which exhibits freely projecting legs, are coupled through the medium of the legs along their length to define one hollow post. The two part construction of the post provides for connection of girders to each part in a manner that girders may tightly connected to the post in directly aligned pairs.

Abstract: In order to reduce the sound emission, in transformers of this type resonators are arranged between the active part and a tank which surrounds this active part and is used as a reservoir for the cooling fluid. According to the invention, two plates (9, 10), connected to one another at least at their edges in a vacuum-sealed manner are used as resonators, at least one (10) of which plates has bulges (11) projecting into the oil chamber (8) in the form of a lens, the space in the bulges (11) between the plates (9 and 10) being almost free of gas and empty of air. The use of such resonators is particularly expedient in high-power transformers in order to reduce vibration which is emitted to the cooling fluid, and is generated magneto- strictively by the iron cores and is generated electrodynamically by the windings. <IMAGE>

Abstract: A source voltage build-up detecting circuit detects, after the source is switched on, whether a source voltage (Vcc) is higher than a predetermined voltage, and produces a detecting signal. The circuit comprises a complementary metal-oxide semiconductor (CMOS) inverter (TR2, TR3), a level shifting element (TR6) connected between the power source and the CMOS inverter, and a voltage generating circuit (Ca, TR14, TR15) connected to the input of the CMOS inverter. The level shifting element supplies a voltage lower than the source voltage to the CMOS inverter as a working voltage. When the source voltage is lower than the predetermined voltage after the source voltage is switched on, the voltage generating circuit outputs a voltage higher than the threshold voltage of the CMOS inverter, and when the source voltage becomes higher than the predetermined voltage, the voltage generating circuit outputs a voltage lower than the threshold voltage of the CMOS inverter.
